Abstract (en)
Embodiments include a wafer-on-wafer bonding structure where each wafer includes a seal ring structure around die areas defined in the wafer. Embodiments provide a further seal ring spanning the interface between the wafers. Embodiments may extend the existing seal rings of the wafers, provide an extended seal ring structure separate from the existing seal rings of the wafers, or combinations thereof.
